MAKING SUGAR BLOCKS OR CU BES':

SPECIFICATION formingpart of Letters Patent No. 240,721, dated April 26, 1881..

Application filed March 10, 1581. (No model.)

To all whom it may concern:

Be it known that I, GEORGE JAGER, the younger, a subject of the Queen of Great Britain, residing at Liverpool, in the county of Lancaster and Kingdom of England, have invented certain new and useful Improvements in Making Sugar Blocks or Cubes; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention is best described by aid of the accompanying drawings of mechanism for carrying out my process, in which- Figure 1 is a plan of a mold, and Fig. 2 an elevation of mold and plate E underneath, (described in detail farther on Figs. 3 and 4, elevations of apparatus for filling molds; Figs. 5 and 6, elevations of press for punching the blocks of sugar from the molds; Fig. 7, )lan showing baskets fitted into centrifugal machine; Figs. 8 and 9, views of a wire basket.

The process is as follows: The boiled mass or semi-fluid mass, as it is taken from the vacuumpans, while still hot, is passed into the heater or receiver A. This is provided with a hose or spout, B, and cock 0, for transferring the sugar onto the mold-plates D D. These plates are constructed so as to exactly fit the press hereinafter described, and are pierced with numerous square parallel-sided holes,as shown. 7

Instead of square holes, however, round, hexagonal, or other shaped holes may be used; but the punches of the press hereinafter described must be made to correspond. These moldplates are cast or planed true on each side and laid on a second plate, E, with a piece of calico, canvas, or other cloth, F, between, to make a joint and to absorb a portion of the sirup, thus making the block of sugar hard enough to be punched out after standing an hour or so.

Gr is a traveling belt supporting the plates E, running on smooth-flanged pulleys. It can be supported at intervals by carrying-rollers H, as shown.

I is'a spreader or scraper, turned at a right angle at each side, as broad as the mold-plates, and so placed that as the plates are drawn or slid under it this scraper scrapes all the superfluous sugar forward over the molds, thus further tending to fill them.

I Although only a carrying-belt is shown, a railway and series of carriages, or a slide or gauntree and sliding carriages can be substituted, and the lower plates, E, can be fitted so as to act as sliding or running carriages. These lower plates can, however, be done away with, and in their place a series of loose plungers can form the bottom of the holes. These have this advantage, that they can be themhereinafter described, as they can be forced up against a flat surface, placed above the plate D, by a press below pressing against their shanks. This plan, however, I consider inferior to the one already described, as requiring more careful filling, expense, and labor, and I merely mention it as an alternative design, to prevent others claiming it as a fresh invention to get round mine, when it isin reality another form of mine. The plates filled with sugar, the calico, and lower plate are now taken bodily to one side for the sugar to harden. They are then readyfor the punching. For this part of the process the plates E and cloth F are re moved, and the molds are shoved along the gauntree or slide J under the press, being stopped at exactly the right point by a stop or spring-catch. The press, armed with a series of punches, K, then descends, being actuated draulic or machine power, as the case may be, (in large works either of the two latter will be employed,) and the blocks of sugar are driven out, descending on the spout or board N into a basket or other receptacle, or onto aband or carrier, so as to be carried to a hopper, from which they are filled into Wire baskets or per forated boxes, as shown in Figs. 8 and 9, and these are placed in the centrifugal machine in the manner shown in Fig. 7, the baskets being so dimensioned as to exactly fill the periphery of the centrifugal machine. The centrifugal machine is then set in motion and all the moisture forced out that can be expelled. It is then stopped, the baskets taken out, dipped in a trough or receptacle of saccharineliquor, and reinserted in the centrifugal machine. The process is then repeated,and, if necessary,

is effected, till the sugar is sufficiently white, when a blast of hot air is turned on, and thus selves used as punches, instead of the ones by the handle L and eccentric M, or by by a second or third dipping and centrifugaling the sugar is stoved before leaving the centrifugal machine.

Having fully described my invention, what I desire to claim and secure by Letters Patent 1. The process of manufacturing cubes or blocks of sugar by taking the hot liquid or semi-liquid mass direct from the vacuum or other evaporating pans and pouring it into a frame of molds, such as D, scraping the surplus matter off, and allowing it to cool in the molds, substantially as described.

2. The process of manufacturing cubes or blocks of sugar by casting the hot liquid or semi-liquid mass into molds with absorbent bottom, allowing the blocks so formed to cool in the molds, and then washing them with sirup, substantially as described.

blocks of sugar by running the sugar into molds formed of a plate full of holes, open at top or bottom, and resting on another plate, with a layer of softer absorbing material between as a joint, 'n'essing'the sugar out of these molds (after it has set and the lower plate has been removed) by means of a press armed with a series of plungers corresponding to the molds after removing the lower plate, as set forth.

4. The process. of manufacturing cubes or blocks of sugar by casting the material in molds, then placing the shapes so formed into baskets fitted into a revolving machine, stopping the machine, again damping the lumps with sirup, and then centrifugaling, continuing the damping and drying until the lumps are sufficiently pure or white, when they can be dried by a blast of hot air let into the centrifugal machine.

5. Thecombination of the spout B andcock or valve 0, bringing the hot fluid sugar from the evaporating-pans or heater, the parallelsided mold-plate D, and the scraper I, just scraping the surface of the moldplate and. scraping the sugary mass into the molds,in the manner specified.

6. The combination of the mold-plate D, with parallel faces, the calico or other cloth, F, and the lower plate, E, for the purposes described.

7. The combination of the slide or gauutree J, the mold-plates l), sliding thereon, the presspiston, with aseries of plungers, K, fitting the molds D, a stop or stops to arrest the moldplate exactly as it reaches the right point on the gauntree, and spout N, for guiding the cubes into a basket or other receptacle, substantially as described.

S. The wire baskets shaped so that when placed around the circumference in a centrifugal machine they form a complete annulus, as and for the purposes described.
